AimsThe aim of this study was to evaluate the effect valve surgery (VS) in infective endocarditis (IE) on 5-year mortality and whether conflicting results reported by previous studies could be due differences their methodological approaches.
To assess seizure frequency in a large French cohort of autosomal dominant early-onset Alzheimer disease (ADEOAD) and to determine possible correlations with causative mutations.A national multicentric study was performed patients ADEOAD harboring pathogenic mutation within PSEN1, PSEN2, APP, or duplication minimal follow-up 5 years. Clinical, EEG, imaging data were systematically recorded.We included 132 from 77 families: 94 PSEN1 carriers (MCs), 16 APP carriers, 15 MCs, 7 PSEN2 MCs....
The objective of this narrative review was to describe the effect microbial-based products, specifically pro- and prebiotics, on gut health, function, disease prevention during early life at weaning in dairy calves. main source data information compiled for peer-reviewed literature. Diarrhea is responsible majority mortality morbidity life. Pro- prebiotics have recently been explored as mechanisms promote health decrease diarrhea young In addition, change calf diet, where there a transition...
The objective of this prospective cohort study was to determine the effect an abnormal fecal consistency score on weight gain and mortality in male Holstein calves identify risk factors associated with occurrence score. This enrolled 2,616 entering a calf-raising facility Ontario, Canada, between January 2018 December 2020. Fecal scores were assigned twice daily for first 28 d following arrival, where 2, indicating runny consistency, 3, watery classified as diarrhea. Severe diarrhea by 3....
Diarrhea is the leading cause of morbidity, mortality and antimicrobial drug use in calves during first month age. Alteration bacterial communities gastrointestinal tract occurs diarrhea. Diarrheic often develop anion gap (AG) acidosis associated with increased concentrations unmeasured anions including D- L-lactate. However, studies investigating association between gut microbiota alterations development acid-base disorders diarrheic are lacking. We investigated fecal diarrhea its changes...
Calves arriving to veal and dairy-beef facilities in poor condition are at risk of future health challenges reduced growth rates, limited knowledge is available on how time transit affects subsequent these animals. The objective this randomized controlled trial was understand the effects transport duration diarrhea, respiratory disease, surplus calves destined for production following 6, 12, or 16 h continuous road transport. Surplus dairy (n = 175; 7 cohorts) from 5 commercial farms...
The objective of this prospective observational study was to investigate associations postpartum health with estrus detection (ED) by activity monitors and pregnancy outcomes in dairy cows. A total 1,743 Holstein cows from 2 commercial herds Ontario, Canada were enrolled 3 wk before expected parturition examined for variables until 9 postpartum. Body condition score (BCS) lameness measured at prepartum, serum concentrations Ca, haptoglobin (Hp), nonesterified fatty acids 6 ± d milk (DIM),...
<h2>ABSTRACT</h2> Our objective was to describe associations of postpartum health with pregnancy and loss (P-LOSS) from d 19 40 after first artificial insemination (AI) in lactating Holstein cows. In 2 commercial dairy herds Ontario, Canada, 468 cows were enrolled 21 ± 3 before expected parturition when body condition score (BCS) lameness assessed. Serum total Ca, haptoglobin (Hp), nonesterified fatty acids (NEFA) measured at 6 DIM. Blood β-hydroxybutyrate (BHB) measurement metritis...

The objective of this retrospective cohort study was to evaluate a K-Nearest Neighbor (KNN) algorithm classify and indicate clinical Bovine Respiratory Disease (BRD) status using behavioral patterns in preweaned dairy calves. Calves (N=106) were enrolled on from one facility for the preweaning period. Precision technologies used record feeding behavior with an automated feeder activity pedometer (automated features). Daily, calves manually health scored (BRD; Wisconsin scoring system, WI,...
Neonatal calf diarrhea is the leading cause of neonatal morbidity and mortality globally. The changes associated with gastrointestinal microbiota in calves experiencing its etiology are not fully understood or completely defined literature. Several studies have demonstrated that fecal experience substantially deviates from healthy age-matched calves. However, one key question remains: whether observed bacterial communities (also known as dysbiosis) a predisposing factor for, consequence of,...
This observational study evaluated the relationship between lung consolidation observed at weaning and calf ADG, association of pathogen shedding on ADG in beef × dairy calves up to 238 d. Beef Holstein (n = 143) were sourced from 2 dairies. Calves managed 3 cohorts fed milk replacer starter preweaning. transported another facility after raised one group where they with oat hay transitioned a corn silage-based total mixed ration diet. Calf was calculated arrival 61 ± 14 d (period 1), 83 21...
